An inverse method of designing cylindrical cloaks without knowing coordinate transformation
Cheng-Wei Qiu, Andrey Novitsky
An inverse way to define the parameters of ideal cylindrical cloaks is developed, in which the interconnection between the parameters is revealed for the first time without knowing…
Goos-Hänchen shifts of an electromagnetic wave reflected from a chiral metamaterial slab
W. T. Dong, Lei Gao, C. W. Qiu
Applying Artmann's formula to the TE-polarized incident waves, we theoretically show that the Goos-Hänchen (GH) shifts near the angle of the pseudo-Brewster dip of the reflection f…
Theory and optimization of transformation-based quadratic spherical cloaks
Andrey Novitsky, Cheng-Wei Qiu
Based on the concept of the cloak generating function, we propose a numerical method to compute the invisibility performance of various quadratic spherical cloaks and obtain optima…
Spherical cloaking using nonlinear transformations for improved segmentation into concentric isotropic coatings
Cheng-Wei Qiu, Li Hu, Baile Zhang +3
Two novel classes of spherical invisibility cloaks based on nonlinear transformation have been studied. The cloaking characteristics are presented by segmenting the nonlinear trans…
Achieving Invisibility of Homogeneous Radially Anisotropic Cylinders by Effective Medium Theory
Yaxian Ni, Lei Gao, Cheng-Wei Qiu
In this paper, we establish the full-wave electromagnetic scattering theory to study the electromagnetic scattering from infinitely long cylinders with radially anisotropic coating…
Electromagnetic interaction of arbitrary radial-dependent anisotropic spheres and improved invisibility for nonlinear-transformation-based cloaks
Cheng-Wei Qiu, Andrey Novitsky, Hua Ma +1
An analytical method of electromagnetic wave interactions with a general radially anisotropic cloak is established. It is able to deal with arbitrary parameters (, …
